RehaGait

Gait Analysis Made Simple

Gait analysis is not new. Clinicians have long wanted reliable and objective ways of documenting movement in health and disease. RehaWatch is a product designed to make gait analysis practical for clinical use.

RehaGait is an easy to use, clinically valid gait analysis system. Ideal for documenting patient progress without the complexity of many alternative systems.

Whether you are a doctor, a therapist or a trainer – RehaGait provides objective, and time-saving assessment of movement disorders. The CE-certified system is already used today as medical product in all fields of rehabilitation for the therapy of gait and movement restrictions.

Special software and sensors provide extensive opportunities for researchers and developers in biomechanics and movement sciences.

Technical Aspects - Sensor Technology

The system utilises triaxial accelerometers, gyroscopes, and magnetometers (a total of 9 Degrees of Freedom). The sensor is an inertial measurement unit (IMU) controlled by a microcontroller. It can be integrated into a sensor network via Bluetooth.

Linear acceleration as well as angular velocity of complex motion sequences can be recorded with high sampling rates of up to 600 Hz. The highly configurable IMU offers multiple advantages:

freely configurable (sampling rate, measurement mode etc.)

internal memory (4 GB)

long battery life (11 hours)

wireless

calibrated

compact

flexible straps

The internal memory allows continuous data storage on the sensor. Therefore, the permanent connection to a receiver is not necessary.

Extend the mobility and flexibility of your application by using the portable RehaWatch receiver.

MotionLab – modular software for motion analysis

Clinical analyses and tests with the RehaWatch system can be performed easily, quickly, and objectively. The software provides individual solutions for PC or tablet. All modules are freely configurable and can be integrated in MotionLab. The use of the MotionSensor allows a real-time and location-independent analysis of the measurement.

Data analysis possibilities

The analysis system is focused on the aspects of walking, which can be regarded as an indicator for gait quality. During walking, the foot movement is measured, especially the patterns of acceleration and angular velocity that occur. On this basis, gait variables are calculated:

RehaGait system

Portable - use anywhere

Spatial-temporal parameters

Stride duration (s)

Stride length (m)

Cadence (/min)

Velocity (m/s)

Foot angle (°)

Ground clearance (cm)

Foot height (cm)

Circumduction (cm)

Gait phases (Modelled after J. Perry)

Periods

Functional tasks

Single gait phases

These gait parameters represent a measure for gait quality and are checked for compliance with specific normal ranges. Left-right-symmetries are calculated for all bipedal parameters.
